Noroxi assessment

Priority: This week (action score 73/100)

  • CISA has confirmed exploitation in the wild (May 20, 2024). Remediation deadline for US federal agencies: Jun 10, 2024.
  • Probability of exploitation in the next 30 days: 15.2% (FIRST EPSS); higher than 96.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Microsoft Edge (Chromium-based) 124.0.2478.109.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to Microsoft Edge (Chromium-based) 124.0.2478.109 or later.
